The Health Minister has advised Malaysian men against using unregistered aphrodisiacs, commonly referred to as "ubat kuat lelaki" as these products contain scheduled poisons.

Apparently most of these products sold in the market generally contain poisons like sildenafil, tadalafil and verddanafil.

The Health Minister told a local daily that these 3 drugs, normally used to treat erectile dysfunction, can only be prescribed by a doctor or registered pharmacist and misusing these poisons can lead to health problems such as heart attack, stroke, brain haemorrhage, high blood pressure, and loss of hearing and sight.

There are loads of "ubat kuat lelaki" in the market which obviously feeds the high demand for them. I've even seen advertisements pasted under a flyover.
